CVE-2026-46211

CVE-2026-46211 affects the Linux kernel drm/msm/gem component. The flaw in msm_ioctl_gem_info_get_metadata() can cause a NULL pointer dereference due to unchecked allocation (kmemdup()) and always returning 0 on errors, making userspace believe success. The issue is fixed by adding a NULL check f...

In the Linux kernel, the following vulnerability has been resolved: drm/msm/gem: fix error handling in msmioctlgeminfogetmetadata msmioctlgeminfogetmetadata always returns 0 regardless of errors. When copytouser fails or the user buffer is too small, the error code stored in ret is ignored becaus...

CVE-2026-46197

The CVE-2026-46197 issue affects the Linux kernel DRM/AMDKFD component, where the nattr field validation for SVM ioctl was insufficient against the reported buffer size, enabling out-of-bounds access via a user-controlled attribute count. The root cause is input size validation failure in the SVM...

CVE-2026-46167

In the Linux kernel, the following vulnerability has been resolved: usb: usblp: fix uninitialized heap leak via LPGETSTATUS ioctl Just like in a previous problem in this driver, usblpctrlmsg will collapse the usbcontrolmsg return value to 0/-errno, discarding the actual number of bytes transferre...

CVE-2026-46167

CVE-2026-46167 – Linux kernel usb/usblp heap leak : The vulnerability stems from an uninitialized status buffer (statusbuf) allocated at probe time for LPGETSTATUS. If a malicious printer returns zero bytes, a stale 8-byte heap region could be copied to userspace via LPGETSTATUS, causing a heap l...

CVE-2026-46159

The CVE-2026-46159 issue affects the Linux kernel’s Btrfs code, specifically btrfs_ioctl_space_info(). A TOCTOU race occurs between two passes over block group RAID type lists: the first pass counts entries for allocation, the second fills the buffer and releases the groups_sem lock. If entries s...
